Mac Mail App Icloud Client Host Rejected Access Denied
Siri Vonbank
when I try to send mail, I get this message: The server response was: : Client host rejected: Access denied. I have tried a custom smtp server set up I found in the forums here, and that doesn;t go through either. Also when I go to system preferences and go to iClocud, my system preferfence freeze and I have to force quit it to get out. So I can't remove icloud from the list and try re-setting it up. Any help would be appreciated.
Worst of all, I cannot send email from iCloud. When I try to send, it says: "Client host rejected: Access denied." I can send from the iCloud webpage, from my iPad and from my Phone. All on the same network, same login ID, etc.
Hi can you help me about my problem because i was abit desperate.Unable to email via SMTP.xxx.xxx.xxx Failed to add recipient: xxx...@gmail.com [SMTP: Invalid response code received from server (code: 554, response: 5.7.1 : Client host rejected: Access denied)
If you do authenticate properly, you can still end up with this error however. The recipients server can deny the relay, if their spam filters have detected the email as spam, or as coming from a spam source (IE: your server is on a blacklist). If this happens, then their server rejects the email, and you will again get a relay access denied error.
Probably 80% of our calls and support tickets regarding email issues in general, not just relay denied errors, are caused by the customer having incorrect settings. If you are certain that your server is working fine, then you should go over the settings with your client to ensure they have everything configured correctly to work with your server.
Note that this requires you to set a very small delay time like 1 second in /etc/default/postgrey (Debian & Ubuntu) or /etc/sysconfig/postgrey (CentOS/RHEL). The delay time tells the SMTP client how many seconds to wait before sending again. If the delay time is not small enough, then the second email delivery would still be rejected.
I think you fail to properly explain the repercussions that enabling reject_unknown_reverse_client_hostname and reject_unknown_client_hostname can have. First of all I think it is important to make it clear that setting these effectively makes sure that your mail server will not accept mails from people running their own mail servers on home internet connections where the PTR is either rarely set or can not be changed by the customer.
